摘　　要：The study of pattern dynamics in a Hamiltonian system(HS)having an infinite number of degree of freedom is very difficult due to the absence of attractors in such system.In this letter,we propose a useful method that only a few representative manifolds in phase space are investigated,and it can be used to reveal the pattern formation of HS.The conserved cubic Schrödinger equation is discussed.Although a special model is chosen,this method can be applied to more general case such as the near-integrable HS.
